Fdn. Drains Connect to Roof Drains
(OP)
What are some opinions regarding foundation and underslab (slab on grade) drainage systems that connect to roof drains that connect into the storm water system. Are there concerns of backflow. What if the existing storm line pipe is below the foundation/underslab drains?
Thanks
Thanks

If we use a check valve on the foundation drain this would mitigate hydrostatic forces due to backflow water.
